Esteban Aurelio Diaz, 32, was fatally shot just after midnight on July 10, 2019, inside The Mecca, a bar on Main Street in Porterville, California. Emergency responders pronounced him dead at the scene. Witnesses said a suspect approached Diaz from behind, shot him, and fled the bar immediately after the shooting.

The Porterville Police Department opened an intensive homicide investigation. Detectives executed multiple search warrants that recovered 17 firearms — including handguns, rifles, and assault rifles — hundreds of rounds of ammunition, cocaine, a ballistic vest, ski masks, and gloves. Several people were arrested and surveillance footage from the bar captured the shooting.

Investigators continued to gather evidence and pursue leads while urging anyone with information to come forward. Did anyone in the area that night notice something that could help the investigation?
